An allyl terminated hyperbranched polyester (HBP) was added to an epoxy formulation containing a trithiol compound to perform a thiol-ene click reaction. By this procedure a flexible thioether network was formed. The ...

A kinetic model for thiol–epoxy crosslinking initiated by tertiary amines has been proposed. The kinetic model is based on mechanistic considerations and it features the effect of the initiator, hydroxyl content, and ...

Dual curing is the methodology for obtaining thermosets by combining two different and compatible polymerization reactions, taking place sequentially or simultaneously. Sequential dual-curing processing enables the preparation ...

The use of commercially available hyperbranched poly(ethyleneimine)s (Hbpei, LupasolTM, BASF) as curing agent of DGEBA has been studied. HBpei can react with epoxy monomers by an epoxy-amine condensation mechanism and get ...

The anionic copolymerization of a Diglycidyl ether of bisphenol A (DGEBA) epoxy resin and a bislactone has been studied with different initiators. The kinetics of the process has been dealt with in detail, and it has ...

S’ha estudiat la copolimerització de resines epoxi amb una spirobislactona com a comonòmer per tal de controlar la contracció química durant el curat i millorar la seva degradabilitat per tal d’afavorir la seva recuperació ...

n the present work, we report the preparation and characterization of a new family of thermosets based on off-stoichiometric anhydride–epoxy formulations in the presence of an anionic initiator. Diglycidyl ether of bisphenol ...

In this work, the kinetics of curing of a new family of interpenetrating polymer networks (IPNs) obtained by co-formulation of a photocurable acrylic resin with a thermocurable epoxy/anhydride mixture is studied. The first ...
